Captain J.A. Hewer

I am working to document some history on Burka and Selian Coffee Estates. This includes the history of Bloom's Arusha Hotel, as this family went on to purchase part of what now is Burka Estates, The New Arusha Hotel, who had extensive contact with the Bloom family. I am also looking for any information on a Captain J.A. Hewer, who bought Burka originally, The origins of the Arusha Coffee Lodge and anything in between. Any letters, pictures, or just little facts would be of great interest to me.

Thank you for your help,
